SPECIFICATION forming', part of Letters Patent No. 699,105, dated April 29, 1902.

' Appnmnuil'fuedrune 8,1901. serial No. 63.759'. (No model.)

Be it known that LAUesT'Us H.- DAVIS, a citizen ofthe United States, residing at Orawj fordsville, in the county of- Montgomery and; State of Indiana, have invented. a new and useful' Carpet-Stretcher,-oi'ivhich the following is a speciication-` n .l y l This invention relates generally to carpet-` stretchers, and more particularly'to one in-I tended to stretch the carpet in t'wo directions Without removing the stretcher from' the car-i pet. The accomplishmentof these-two'operations is highly a'dvi'n tageousff' particularly.' when it is desired to stretch'an'd force thef carpet into the corner of Ya room; and With these objects in View the invention consists, essentially, in providing a block with barbs or prongs adapted to engage the carpet and also in providing the said block with means for moving it both transversely and longitu-k dinally. L

Another object of the inventionis'to provide against projecting thebarbs orfpron'gs'` too far through the carpet; and with' this`ob' ject in view theinvention consists 'in arrang? ing adjustable the block.

The invention has certain other objects and guard-plates at each end 'of'.

advantages the accomplishment of which is obtained by means of various parts' hereinl after fully describedyand pointed out in the claims. Y' p I f In the drawings'forming part of this speci ication, Figurelis a plan vievir illustrating the practical 'applicationmofmy invention. Fig. 2 is a verticalfs'ectional view on the line 2 2 of Fig. 1.' Fig. 3 isf-an end view of the block, showing the adjustable gages.. Fig. 4 is a bottomplan View of the block, showing the adjustable gages and also the prongs for engaging the carpet; and Fig. 5 is a com-v bined crank and hammer.

In the practical embodiment of my invention I employ a Vblock A of any suitable material and of any desired dimensions, the under faceof said block being provided with a series'of-barbs or prongs A', adapted to engage the carpet, so that when the block is moved lthe carpet Will be stretched. These barbs or prongs A' are inclined and are intended to pass through the body or fabric ofV the carpet; but it is not intended that they should come in contact With the iioor or carpet-lining, and in order to prevent thisiI employqadjustable guard-plates B at each end of theflblock, said guard-plates being vertically adjustable bymeans of the vertical slots Y ]3 and screws B2. By adjusting these guardplates uporrdown the projecting portion of the barb orprong is regulated so as to expose atgreater or lesser port-ion `thereof;` for engagement-With the carpet. Y

f The upper face lof the block A isf'formed with a central longitudinal guideway C, in

T'Which slides a bar D. One side o f the guideway C isstraight, while the opposite side is I in cross-section for the engagement of. the optnatling crank or Wrench, hereinafter described. --The pawls D" hold the bar D locked i'n' anydesired adjustment. -G isx'mounted loosely upon the shaft F, the 'hub' of said pinion being circular in crosssection for a portion of its length, as shown A second pinion at G', and square Ain cross-section, as shown at G2, said hub stopping short of `the squared portion ofthe sh aftA F,1asimostclearly shown in Fig. 2. -The circular or cylindrical portion ofthe pinion-huby turns freel'yin2a1housing H, securelyfastened to theslidin'gblock D Within-the guideway, said housing serving as a guide for the rack-frame I, which works therein in a direction at right angles tothe longitudinalline of` the block-A,fsaid frame being essentially rectangular in. shape and comprising the rack-bar I' and the extensions I2 and 13, the extension I2 having a hook K attached thereto to receive a chain L, carrying pins L', which are driven into the iloor at either side of the room. The extension I3 carries a pin M, which is also driven into the oor upon the opposite side of the room.

N indicates the combination hammer, and operating crank or.wrench, having'anopening N in the head, which is adaptedto it upon the squared portion G2 vof 'thepirion G, and also a square opening N2, formed at the end of the handle and adapted to engage the square end F' of the shaft F.

P indicates a pawl pivoted to the housing H and adapted to engage the rack-bar I for the purpose of locking the same.

When it is desired to stretch a carpet by means of my improved carpet-stretcher, the pin L is driven into the iioor at one side of the room and the pin M. is also driven into the door at the opposite side of the room. The block A is then placed upon the carpet and the barbs or prongs forced into the fabric thereof, and the chain L is connected to the hook K, any link of thesaid chain being readily attachable to the said hook. The operating crank or Wrench is then tted upon the squared portion of the pinion G and turned in the proper direction to move the block toward the pin M, and inasmuch as the rackfframe is stationary it will be readily understood that by turning the pinion the block A will be easily moved toward the pin M, thereby stretching the carpet in one direction. Thepawl P is then throw-n into engagement with the rack-bar, locking the block at that point, and the operatinghandle or wrench is then applied to the shaft F, and the block is moved longitudinally in either direction desired for the purpose of stretch-` ing the carpet at a right angle to the direcpet up into the corner of ,a room.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. A carpet-stretcher comprising a block having barbs or prongs for engaging the carpet, a rack-frame arranged upon the said block and adapted to be fixed between two points, and means arranged upon the block for moving itboth in 'a transverse and longitudinal direction, substantially as shown and described.

-2. In a. carpet-stretcher, the combination with a block having prongs or barbs upon its lower face, the upper face of said block havin g a guideway produced therein, said guide- -Way having a -rackfbar at one side, va bar sliding in the guideway,.pinions carried by the said bar, said pinions being arranged one adjustable end guards secured to the ends ofl the block, substantially as and for the purpose described.

4. In a carpet-stretcher, the combination with a block having barbs or prongs upon its under side and a guideway upon its upper side, said guideway having a rack-bar at one side, a bar lsliding in the guideway and provided with; pawls, pinions carried by the sliding bar, one above the other, said pinions being independent of each other, a rack-frame sliding across the face of the block, the uppermost of the pinions being adapted to engage the said rack-frame, ,said yrack-,frame being provided with means for securing the same ina fixed position, and a pawl carried by the sliding bar for the purpose ofv locking thevrack-frame, substantially-,as described.

5,. In a carpet-stretcherethe'combination with a block havingbarbsor prongs upon its under face and a longitudinal guideway having a vrack-bar at one side,- `a sliding bar working in the guideway, a pinion jon-rnaled 0n the sliding bar 4and adapted to engagel the rackbar of the block, pawls carried -by the sliding bar for engagement with the said rack-bar, a rack-frame extending across the face of the block and having a chain 4attached to one end and a pin'at the opposite end, a

housing attached to the sliding bar and straddling the rack-frame, a pinion arrangedwithin the housing and rack-frame and adapted for engagement with the said rack-frame, a pawl pivoted to the housing and adapted to engage the rack-frame, and means for rotating the pinions whereby the block is moved transversely and longitudinally as set forth.
